5-3. OCR Setting Procedure
CAUTION
OCR setting changes must be performed by competent persons.
After setting changes are made, the settings be checked with e.g., a type ANS2S OCR test interface unit (optional).
After completion of OCR tests, be sure to return the settings to the original values. Failure to do so may cause a fire or
burnout.
Before changing OCR settings, open the ACB and then lock the OFF button to prevent the ACB from being closed
inadvertently.
Use the cross slot screwdriver or small flatblade screwdriver with a torque of not more than 0.1 N·m or a force of not more
than 0.1 N when adjusting the setting switches (rotary step switches or slide switches). An excessive torque or force may
cause a malfunction.
The following describes how to set the OCR.
1) Open the ACB.
2) Push the right end of the OCR cover to the left at the hollow on the front cover to unlatch and open the OCR cover. See Fig. 20.
If the OCR cover is padlocked, first remove the padlock.

3) Use rotary step switches and slide switches to set the OCR. See Fig. 21.
Rotary step switches must be adjusted with a cross slot screwdriver. Turn switch knobs stepwise and do not stop the knobs
halfway between calibration markings. A bold line on a switch dial means the same settings.
Slide switches must also be adjusted with a small flatblade screwdriver. Do not stop switch knobs halfway.
